C26000 Brass (CuZn30) – For Deep Drawing, Stamping & Forming
Product Introduction
C26000 brass is one of the most widely used grades in copper-zinc binary alloys. It is also an α single-phase brass with approximately 70% copper and 30% zinc content. Its core feature lies in its excellent cold working performance and good strength, and it is hailed as the most ductile brass among copper alloys. In the family of copper alloys, C26000 belongs to a universal and cost-effective material.

Key Features
Excellent cold working performance C26000 exhibits extremely high ductility and toughness, making it ideal for severe plastic deformation processes such as deep drawing, stretching, bending, and cold heading. This is the fundamental reason why it was selected as the material for bullet casings.
Good balance of strength and plasticity It is soft and easy to shape in the annealed state, and its strength can be increased by more than double after cold processing, while still retaining a certain degree of plasticity.
Good electrical and thermal conductivity The conductivity is approximately 28% of pure copper, which is a relatively high level among copper alloys. It is suitable for parts that require both electrical conductivity and shape.
Good resistance to general corrosion It performs well in air, fresh water, steam, and non-oxidizing acid solutions.
